Fitness Levels Impaired in Patients With Paediatric IBD
Patients with paediatric inflammatory bowel disease (IBD) exhibited lower cardiorespiratory and neuromuscular fitness than healthy matched control participants. Higher body mass index (BMI) for children and adolescents was negatively associated with cardiorespiratory fitness, while the use of any biologic medication was positively associated.
METHODOLOGY:
This cross-sectional case-control study assessed cardiorespiratory and neuromuscular fitness in patients with paediatric IBD aged 6-17 years.
This study included 73 patients with paediatric IBD (mean age, 13 years; 56.2% girls; 31 with Crohn's disease [CD]; 42 with ulcerative colitis [UC] and IBD unidentified) from two tertiary centres in Finland and 73 age- and sex-matched healthy control children from an ongoing study and registry.
Clinical disease activity was determined using the Pediatric Ulcerative Colitis Activity Index for UC and using the Pediatric Crohn's Disease Activity Index for CD along with the Physician's Global Assessment, and physical activity was evaluated using a questionnaire covering various activities over the past 12 months.
Cardiorespiratory fitness was measured with a maximal exercise test on a cycle ergometer. Peak oxygen uptake (VO2peak) and maximal workload (Wmax) divided by body weight were considered as measures of cardiorespiratory fitness.
Neuromuscular fitness was also assessed using various tests.
TAKEAWAY:
All patients with CD were in remission or had mild disease activity, whereas 69% of patients with UC were in remission and only one had a severe disease.
Patients with paediatric IBD had significantly lower cardiorespiratory fitness, with lower Wmax/kg ( P = .007) and VO2peak/kg ( P < .001) than control participants.

IN PRACTICE:
"Lower physical fitness has been associated with poorer disease control, impaired quality of life, and increased risk of cardiovascular diseases in PIBD [paediatric IBD]. This emphasizes the importance of assessing and improving physical fitness in these patients as a part of their multidisciplinary treatment," the authors wrote.

LIMITATIONS:
Some data from the control group were collected previously, and changes in physical activity levels over time may have affected the results. Additionally, the duration of the disease in patients was short, and the design was cross-sectional.
